Belching during Fasting
Issue No. 1393- If a person who is fasting is certain that if he belches something will come out of his throat, he should not belch intentionally, but there is no harm if he is not certain about it. However, if as a result of belching involuntarily, something comes into his throat or mouth, he should throw it out, and if he intentionally swallows it, his fast will be void but there is no harm if it is swallowed involuntarily.
